VitalQIP Product Description
3.37 DHCP Failover
Alcatel-Lucent's VitalQIP supports configuration of failover servers. Failover of this server is provided as
many-to-one failover server (one backup for many primaries). ALU DHCP failover uses a heartbeat
mechanism to detect if a server goes down.
Upon loss of connectivity between a primary and a failover, the failover server will wait a specified time
interval, which is configurable, before becoming active. This can be configured to be nearly
instantaneous. Once the configured time interval has passed and the failover cannot re-establish
communication with the primary DHCP server it will begin responding to lease requests.
When the Primary DHCP server is brought back online the secondary will be notified through the heart
beat. This will initiate an update of the failover lease database using the primary as the authority. This
then results in the primary seeing and handling the request.
3.38 Third-party DHCP Servers
VitalQIP software provides the ability to manage and configure selected third-party DHCP servers, their
configuration files, and active leases. These servers are:
•
Microsoft Windows DHCP
3.39 Database and DDNS Updates
By integrating the DHCP process with the enterprise server and DNS servers, DHCP provides real-time
updates to the VitalQIP database and dynamic DNS servers. Alcatel-Lucent also provides a message
queue that handles these updates and guarantees message delivery to the database or DNS servers.
The message queue allows the administrator to configure how updates should occur:
•
VitalQIP Database
•
DNS
•
Both
•
DNS Backup – If the database is not available, continue to update DNS.
Should either the VitalQIP database or DNS (depending on the policy above) be unavailable, the message
queue service will continue to retry the updates until successful.
3.40 VitalQIP Administration
One of the most powerful features of the VitalQIP software is the ability to distribute IP management
responsibilities within divisions and departments of a company.
The administrator policies establish the individuals who will manage the network or portions of the
network and what impact they will have on their assigned portions. Alcatel-Lucent provides multiple
levels of administration.
Multiple User Interfaces- Network managers and administrators can utilize their tools of choice to work
with VitalQIP software. Comprehensive graphical user interfaces running on either Windows
